Professional Domestic Sewage Treatment Equipment, for Urban Residential Areas

PP Integrated Sewage Treatment Equipment

PP integrated sewage treatment equipment is a new-generation, modular, and environmentally friendly decentralized wastewater treatment device independently developed for domestic sewage and low-concentration industrial wastewater treatment. Different from traditional carbon steel and concrete sewage treatment facilities, this equipment adopts high-strength modified polypropylene (PP) as the main structural material, integrating anaerobic reaction, anoxic denitrification, aerobic biodegradation, sedimentation, disinfection, and automatic control systems into a compact and integrated unit. It perfectly solves thepoints of large floor area, easy corrosion, short service life, complicated construction, and high maintenance cost of conventional sewage treatment equipment, and has become a mainstream solution for small and medium-scale sewage treatment projects worldwide.

Superior PP Material Performance

The most prominent advantage of the equipment lies in its superior PP material performance. Modified polypropylene material features excellent acid and alkali corrosion resistance, anti-aging property, and oxidation resistance. It can long-term adapt to complex sewage environments containing organic matter, grease, and trace chemical components, without rusting, cracking or permeating. Compared with carbon steel equipment that requires regular anti-corrosion  and concrete pools that are prone to leakage and weathering, the PP integrated structure maintains stable physical and chemical properties in both underground buried and above-ground exposed environments. Its service life can reach more than 30 years, greatly reducing later replacement and maintenance costs for users and improving the long-term operational stability of the sewage system.

Advanced Treatment Technology

In terms of treatment technology, the equipment adopts mature and efficient A/O biological treatment process, which scientifically divides the internal space into multiple independent functional areas. In the anaerobic zone, macromolecular organic pollutants in sewage are decomposed and hydrolyzed into small molecular substances, effectively reducing sewage COD and BOD indicators. In the anoxic zone, denitrifying bacteria complete nitrogen removal reaction to solve the problem of total nitrogen exceeding the standard. In the aerobic zone, high-efficiency aerobic microorganisms further degrade organic pollutants, while realizing nitrification and phosphorus removal. After layered sedimentation and precise disinfection, the effluent water quality is stable and up to standard, fully meeting the requirements of national and international sewage discharge and reuse standards. The whole treatment process is carried out in a closed tank body, which completely avoids sewage leakage, odor overflow and secondary environmental pollution.

Easy Installation and Operation

In terms of installation and operation, the PP integrated sewage treatment equipment has obvious application advantages. The integrated modular design realizes factory integral production and overall delivery, with no need for complicated civil construction and assembly on site. It supports flexible installation methods such as buried, semi-buried and ground placement, occupying extremely small land resources and effectively saving project land investment. The equipment is equipped with an intelligent automatic control system, which can realize automatic water inflow, aeration, sedimentation and discharge. It supports 24-hour uninterrupted stable operation with low energy consumption and low noise, and basically no special personnel on duty is required after normal commissioning, greatly saving labor and operation costs.

Wide Range of Applications

With its stable performance, durable structure, simple operation and cost-effective advantages, this equipment is widely applicable to decentralized sewage treatment scenarios, including rural residential areas, urban community communities, hotels, resorts, schools, hospitals, scenic spots, catering streets, and small processing factories. It is especially suitable for areas with scattered sewage discharge, small water volume and insufficient supporting pipe networks, making it an ideal energy-saving and environmental protection facility for domestic sewage purification and ecological environment improvement.
